4.2 Electrical connection

DANGER

Voltage on the device

Electric shock

→ Always connect a protective earth first.

→ Check the protective earth.

DANGER

Faulty insulation

Risk of fatal injury from electric shock

→ Use only cables that meet the specified installation

regulations for voltage, current, insulation material, capacity,

etc.

→ Route cables so that they cannot be touched by any

rotating parts.

DANGER

Electrical charge (>50 µC) between phase conductor and

protective earth connection after switching off supply

with multiple devices connected in parallel.

Electric shock, risk of injury

→ Ensure sufficient protection against accidental contact.

Before working on the electrical hookup, short the supply

and PE connections.

CAUTION

Voltage

The fan is a built-in component and has no disconnecting switch.

→ Only connect the fan to circuits that can be switched off with

an all-pole disconnection switch.

→ When working on the fan, secure the system/machine in

which the fan is installed so as to prevent it from being

switched back on.

NOTE

Device malfunctions possible

Route the device's control lines separately from the supply line.

→ Maintain the greatest possible clearance.

Recommendation: clearance > 10 cm (separate cable

routing)

NOTE

Water ingress into wires or cables

Water ingress at the customer end of the cable can damage the

device.

→ Make sure the end of the cable is connected in a dry

environment.

Only connect the device to circuits that can be switched off with

an all-pole disconnection switch.

4.2.1 Requirements

; Check whether the information on the nameplate matches the

connection data.

; Before connecting the device, make sure the power supply matches

the device voltage.

; Only use cables designed for the current level indicated on the

nameplate.

For determining the cross-section, note the sizing criteria according

to EN 61800-5-1. The protective earth must have a cross-section

equal to or greater than that of the phase conductor.

We recommend the use of 105 °C cables. Ensure that the minimum

cable cross-section is at least

AWG 26 / 0.13 mm².

Protective earth contact resistance according to EN 61800-5-1

Compliance with the resistance specifications according to EN 61800-5-

1 for the protective earth connection circuit must be verified in the end

application. Depending on the installation situation, it may be necessary

to connect an additional protective earth conductor by way of the extra

protective earth terminal provided on the device. The protective earth

terminal is located on the housing and provided with a protective earth

symbol and a hole.

4.2.3 Reactive currents

Because of the EMC filter integrated for compliance with EMC

limits (interference emission and immunity to interference),

reactive currents can be measured in the supply line even

when the motor is at a standstill and the line voltage is switched

on.

● The values are typically in the range < 500 mA.

● At the same time, the effective power in this operating state

(operational readiness) is typically < 6 W.

4.2.4 Residual current circuit breaker (RCCB)

If the use of a residual current device (RCD) is required in your

installation, only AC/DC-sensitive residual current devices

(type B or B+) are permissible. As with variable frequency

drives, residual current devices cannot provide personal safety

while operating the device. When the device power supply is

switched on, pulsed charging currents from the capacitors in the

integrated EMC filter can lead to the instant tripping of residual

current devices. We recommend the use of residual current

circuit breakers (RCCB) with a trip threshold of 300 mA and

delayed tripping (super-resistant, characteristic K).

4.2.5 Leakage current

For asymmetrical power systems or if a phase fails, the

leakage current can increase to a multiple of the nominal value.

When connecting, ensure that no wire ends fan out.

Fig. 2: Connecting wires to terminals

; Seal the terminal box.

4.3.3 Cable routing

Water must be prevented from reaching the cable gland along the cable.

NOTE

Damage caused by moisture penetration.

Moisture can penetrate into the terminal box if water is

constantly present at the cable glands.

→ To prevent the constant accumulation of water at the cable

glands, the cable should be routed in a U-shaped loop

wherever possible.

→ If this is not possible, a drip edge can be produced by

fitting a cable tie directly in front of the cable gland for example.

Fans installed lying flat

Make sure the cable is routed in a U-shaped loop.

6.1 Cleaning

To ensure a long service life, check the fans regularly for proper

operation and soiling. The frequency of checking is to be adapted

accordingly depending on the degree of soiling.

DANGER

Risk of injury from rotating fan.

→ Only clean when not in motion. Do not disconnect the fan

from the power supply, just switch it off via the control input.

This will prevent start-up of the fan.

; Dirt deposits on the motor housing can cause overheating of the motor.

; Soiling of the impeller can cause vibration that will shorten the service

life of the fan.

; Severe vibration can destroy the fan.

; In such cases, switch off the fan immediately and clean it.

; The preferred method of cleaning is dry cleaning, e.g. using

compressed air.

; Do not use aggressive cleaning agents!

NOTE

Damage to the device during cleaning

Malfunction possible

→ Do not clean the device using a high-pressure cleaner.# Do

not use acid, alkali or solvent-based cleaning agents.

→ Do not use any pointed or sharp-edged objects for

cleaning.

; Completely remove any cleaning agents used.

; If severe corrosion is visible on load-bearing or rotating parts, switch

off the device immediately and replace it.

; Repair of load-bearing or rotating parts is not permitted!

; Operate the fan for 2 hours at maximum speed so that any water that

has ingressed can evaporate.

; If cleaning does not eliminate vibrations, the fan may need to be

rebalanced. To have it rebalanced, contact ebm-papst.

; The fan is equipped with maintenance-free ball bearings. The lifetime

lubrication of the ball bearings is designed for a service life of 40,000

hours.
